qcacld-3.0: Properly export qos_release_command()

We want to enable the -Wmissing-prototypes compiler switch. Currently
when enabled there is a build failure due to qos_release_command() not
having a prototype. Add a proper prototype, and remove the associated
extern declaration from sme_api.c that is no longer required. In
addition remove adjacent obsolete prototypes.
